Answer:
Option (C)
Explanation:
The changing climatic condition has a direct impact on the available water on earth. This includes the following-
- Mitigation of moisture content in the soil which can be due to the increasing temperature or hot weather condition, and lack of rainfall in a particular region.
- Reduction in the snowpack can also result due to the increasing temperature in the atmosphere and higher amount of incoming solar radiation.
- Changes in the precipitation also can be a factor showing the relationship between the water and the changing climatic condition. This precipitation differs from one place to another.
- Intrusion of saline water into the freshwater region also takes place due to the increasing mean sea level.
Thus, the correct answer is option (C)- all of the above.
